FarDriver actually has a setting that activates regen at throttle-zero. That setting doesn't work well in the PC app right now (at least this was the case a month ago), so use the phone one for that.

Yes, that's fair. I'd focus my efforts and money elsewhere, TBH, but to each their own. I mainly posted here to quell that belief that you can sink heat through a 1cm^2 cross section of copper - which you can't in any meaningful quantity.

Sorry, I'm not sure what you're suggesting with this post-link. From a brief reading, it looks like they're talking about reducing wire-losses and wire heat by going higher gauge. That's totally a thing, but won't cool your motor unless you replace the wires inside the motor. Bumping up the...

I don't have a Sabvoton (they get too expensive when looking at >400A boost @ 72V), but I now have had a FarDriver for a little while. FarDrivers are cheap, feature-rich and easy to operate/program. Why wouldn't I buy one? I use my ND84530 for reverse, speedometer (since my emotorcycle's...

I didn't turn on regen on my bike eventually. Wanted to play around with it first. Get a better feel of the controller before I get greedy. I did test throttle-zero regen on my test-stand quite a bit (also tested brake-regen, but only briefly), and yes, it was very clear the motor was...

Now I can ride recursively

Once self-learning is complete, the controller shouldn't reinitiate it, even if you power it off/disconnect it from the battery. Seems like either the process didn't complete for you, or the controller is defective. Can you show us your throttle settings and your throttle voltage when not...

This is just my test stand. Those are 1meter long 3.5mm^2 wires. They can realistically carry up to 30A continuously, and probably twice that much momentarily. I don't run the motor at anywhere near full capacity. It's a no-load, mostly low RPM test, and even that is only for a few seconds to...

CAT6 fits the RJ45 plug just fine. You didn't give enough information to answer your question. Also, this has nothing to do with battery tech

So, if any of you have read my post about losing my old controller (Sevcon Dragon 8 ), you know Votol was a huge disappointment for me. However, my Fardriver ND84530 just arrived a few days ago and it's everything I hoped for and more. I got motor-spin as almost soon as I hooked up the battery...

OK, so Votol's officially in my frock'it bucket. That was a terrible experience, but luckily, I got my Fardriver (details in separate post, since I'm no longer looking for a new controller). At least I got some teardown pictures of the Votol EM30s to share:

First off, it's cool that you're going to build your scooter. Good luck. Regarding the parts: 1. You wrote "motors", plural. I don't think you should use more than one 3kW motor on something as lightweight as a stand-up scooter. Even just a single 3kW seems like a massive overkill. I ride a...

Sounds like a solid advise, but my USB adapter must've died. I get an error on my PC when I plug it in (even when disconnected from the controller). It would fault-out often (had to disconnect from both PC and controller and reconnect), so I guess it finally kicked the bucket. Or maybe the...

Hi. I'm trying to hook up a mystery 6kW 14" hub motor to EM30p after my original Sevcon controller died. The goal isn't to actually use the motor with this controller. I get that EM30s is hopelessly underpowered for it. I ordered it just to test whether I can get my motor running with a Votol...

Fixed my faults by hooking up my throttle to the controller. It still didn't work. At first SIA rep helped me configure the port settings (told me to set PC15 to "empty_func"), but when she realized I'm not using a QS motor she immediately ghosted. So back on my own, no motor-spin yet, just a...
